displeasure
happiness
orderliness
anger
Answer is Right!
Answer is Wrong!
The correct answer is D. anger.
The other options are incorrect because they do not accurately describe the feeling of indignation. Displeasure is a mild form of dissatisfaction, while happiness is a positive emotion. Orderliness is a state of being organized and neat, and it is not a feeling.
Indignation is a feeling of strong displeasure or resentment aroused by something considered unjust, offensive, or insulting. It is often accompanied by anger and a desire to take action to right the wrong. In the context of the question, the indignation of the retreating troops resulted in large-scale killings because they were angry and felt that they had been wronged.
